BROCKTON – Darnell Moody walked out of Brockton District Court a free man on Thursday after prosecutors dropped a first-degree murder charge that they had filed against him just days earlier.

“We’re no longer going to prosecute this case,” said Russ Eonas, a spokesman for Plymouth County District Attorney Timothy Cruz. “We had received additional information subsequent to his charge and that information cast doubt upon the viability of the charge.”

However, Eonas declined to elaborate as to what the additional information was.

“That’s it,” said Lefteris Travayiakis, Moody’s attorney. “He’s been released on personal recognizance.”

On Tuesday, Moody, 29, of Laureston St., Brockton, was arrested and arraigned for first-degree murder in the shooting of Quentin Phillips, 28, of Mattapan.

Phillips was sitting in a car in a parking lot behind 11 Crescent St., when he was shot in the chest around 2:20 a.m., on Saturday, said Bridget Norton Middleton, spokeswoman for the Plymouth County District Attorney’s office.

Friends drove Phillips to a Brockton hospital where he was later pronounced dead. The killing is the city’s ninth homicide this year.

Family members described Phillips as a quiet man who was a good father to his 4-year-old son. He had a large family, most of whom live in Brockton and Boston, family members said.

Eonas said Phillips’ murder remains under investigation and that no one else has been charged in the case at this time.
